Description

A kind of touch digital display calliper

Technical field

The utility model relates to slide calliper rule technical field, refers more particularly to a kind of touch digital display calliper.

Background technology

Existing digital display calliper, the button adopted is mechanical key, and one is silica gel push-button, is to add conduction carbon granules with silica gel to make, and silica gel plays support and rebound effect, and conduction carbon granules plays conducting effect; Another kind is touch key or is touch-switch, and be make with plastics and metal clips, plastics play a supportive role, metal clips plays conducting effect and rebound effect, also having a kind of is the mutation of above-mentioned the second technology, is exactly the metal clips directly used in touch-switch, is also pot son sheet.

There is following technical matters in above-mentioned prior art, the first, life problems, with silica gel push-button and metal clips can by number of times be limited, will lose efficacy after certain number of times ineffective.The second, slide calliper rule often need to add environment at more severe machine and use, and use silica gel push-button not contact oily matter, otherwise easily will be corroded and break down.3rd, waterproof oil-proof result is poor, although silica gel push-button can accomplish water proof and dust proof, grease proofing effect is bad, and touch key or the young sheet of pot itself more do not have the grease proofing function of water proof and dust proof.

Utility model content

The utility model in view of the foregoing defects the prior art has, a kind of touch digital display calliper is provided, these slide calliper rule comprise blade, chi frame, mainboard, LCD display, case, mainboard CPU, blade is connected with chi frame, LCD display is connected with mainboard, mainboard CPU is integrated on mainboard, and be electrically connected with LCD display, mainboard is connected with chi frame, case is connected with chi frame, these slide calliper rule also comprise transparent protection plate, full conducting conducting resinl, button CPU, tactile sensor, transparent protection plate there is button, transparent protection plate is connected with case and is placed in the upper end of LCD display, full conducting conducting resinl is connected with the button of the transparent protection plate towards mainboard side, the full conducting conducting resinl other end and the tactile sensor be integrated on mainboard are electrically connected, tactile sensor and button CPU are electrically connected, button CPU and mainboard CPU is electrically connected.

Further, the button of transparent protection plate is touch-key.

Further, tactile sensor be capacitance type sensor, resistance sensor, optical sensor, inductance type transducer, electric wave formula sensor, electromagnetic sensor one of them.

Further, transparent protection plate is transparent acrylic.

The utility model compared with prior art; owing to have employed monoblock type transparent protection plate and the structure such as touch-key, full conducting conducting resinl, tactile sensor; extend transparent protection plate button serviceable life; and the service time of machine product; this product transparent protection plate can grease proofing, waterproof and dustproof; improve the performance of product; transparent protection plate can contact with oily matter; improve the adaptive capacity to environment that this product uses; this case compared with prior art; use cost is lower, better effects if.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Accompanying drawing comparative descriptions: 1 blade, 2 chi frames, 3 mainboards, 4LCD display screen, 5 cases, 6 mainboard CPU, 7 transparent protection plates, 8 full conducting conducting resinls, 9 button CPU, 10 tactile sensors, 11 buttons.

Embodiment

Below with reference to accompanying drawing, the technical solution of the utility model is elaborated, so that those skilled in the art better understand and implement this programme.

As shown in Figure 1, this touch digital display calliper comprises blade 1, chi frame 2, mainboard 3, LCD display 4, case 5, mainboard CPU6, blade 1 is connected with chi frame 2, LCD display 4 is connected with mainboard 3, mainboard CPU6 is integrated on mainboard 3, and be electrically connected with LCD display 4, mainboard 3 is connected with chi frame 2, case 5 is connected with chi frame 2, characterized by further comprising transparent protection plate 7, full conducting conducting resinl 8, button CPU9, tactile sensor 10, transparent protection plate 7 there is button 11, transparent protection plate 7 is connected with case 5 and is placed in the upper end of LCD display 4, full conducting conducting resinl 8 is connected with the button 11 of the transparent protection plate 7 towards mainboard 3 side, full conducting conducting resinl 8 other end and the tactile sensor 10 be integrated on mainboard 3 are electrically connected, tactile sensor 10 and button CPU9 are electrically connected, button CPU9 and mainboard CPU6 is electrically connected, further, transparent protection plate 7 is transparent acrylic, the button 11 of transparent protection plate 7 is touch-key, tactile sensor 10 be capacitance type sensor, resistance sensor, optical sensor, inductance type transducer, electric wave formula sensor, electromagnetic sensor one of them, for capacitance type sensor, because full conducting conducting resinl 8 is connected with capacitance type sensor, and as the medium of capacitance type sensor, when not touching the button 11 on the transparent protection plate 7 connecting full conducting conducting resinl 8, capacitive transducer has a fixing charging-discharging cycle, and frequency is fixed and can be measured, if when we touch the button 11 on the transparent protection plate 7 connecting full conducting conducting resinl 8, the specific inductive capacity of capacitor will be increased, charging discharging cycle is just elongated, frequency will correspondingly reduce, we can by the change of measuring period, and detecting touch action, is delivered to button CPU9 the change in electric that associated change causes, pass to mainboard CPU6 after button CPU9 computing, send related data according to setting to LCD display after mainboard CPU6 computing and show.
